Q-I cycled out drone comb through August. Screen bottom board colonies got 4 or 5 powdered sugar treatments. Solid bottom boards got ApiGuard. I gave 3 Apiguard treatments in a row. Some of each died and some of each survived. All dead-outs happened Oct, Nov, and Dec of 2014. One looked like it would make the grade for almonds 10/19 but on 11/25 it was a dead out?!
A- Thank you for sending a survey. The details on use of different control materials depending upon configuration of the hive (sold or screen bottom boards) is useful and we will seek to capture it in our data analysis.
